Pointers

Go has pointers. A pointer holds the memory address of a value.

The type *T is a pointer to a T value. Its zero value is nil.
```go
var p *int
```
The & operator generates a pointer to its operand.
```go
i := 42
p = &i
```
The * operator denotes the pointer's underlying value.
```go
fmt.Println(*p) // read i through the pointer p
*p = 21         // set i through the pointer p
```
This is known as "dereferencing" or "indirecting".

Unlike C, Go has no pointer arithmetic.
